I somehow managed to corrupt my 18 gig XFS filesystem.  It ran
fine for several months, but now it is quite trashed.  I filled it up
with a huge write() call, and then shortly thereafter things started
failing.  I got I/O error reading ".", and couldn't really do much
so I rebooted.

The first time I rebooted, it wouldn't mount the partition.  So I
ran xfs_check on it and got 485k lines of crud.  xfs_repair core
dumped in phase 3, agno = 0 after several "imap claims a free inode..."
and "bad version number 0x0..." and "bad magic number 0x0..." messages.

After subsequent reboots, I can now mount the filesystem, but xfs_repair
still dumps core.  The mounted filesystem has now lost much of it's
contents, and I get messages like this from ls:
ls: /home/sparker/News: No such file or directory

So the question is:  How can I turn this catastrophe into something
useful for the XFS team?  Do you want a copy of the filesystem image?
Will you be able to do anythign useful with it if I send it? It may take
me a few days to get it there, so could I give somebody an account on
this machine to poke at it?  Do you want the output of xfs_check?  

Please let me know how I can be useful.

Thanks,
Steve
